RR(S): JDK-7127191 SA JSDB does not display native symbols correctly for transported Linux cores

[Dmitry Samersoff]

Hi Everyone,

Please review the fix.

http://cr.openjdk.java.net/~dsamersoff/JDK-7127191/webrev.01/

This fix doesn't solve all problems with symbol lookup in SA, but
address the problem mentioned in bug reports.

1. I change algorithm of pathmap_open. Now, it tries to find library
hardly.

2. I decided not to fix broken binary search in loadObjectContainingPC,
because with less then 20 DSO's we typically have here performance of
just linear search is approx the same as load, sort, convert to array
and do binary search.
